ROTARY IIEUMP Application led September 12, 1923. Serial No. 662,302.

To all 'whom t may concern: 1

Be it known that I, ALBERT L. KINs, a citizen of the United States, anda resident of Stockton, in the county of San Joaquin and State ofCalifornia, have invented certain new and useful Improvements in RotaryPumps, of which the :following is a specilication.

My invention relates to improvements in rotary pumps and it consists ofthe con` structions, combinations and .arrangements herein described andclaimed.

A11 object of the invention is to provide an improved4 rotary pumpadapted more particularly for use in deep wells, one ofthe features ofthe pump being an arrangement oi" sustaining the column of water in thedischarge pipe so that the runner is not unnecessarily burdened. p

Another object of the invention is to pro- .vide a deep Well pump inwhich the runner operates beneath a stationary nozzle plate, the waterbeing forced through said nozzles by the runner and sustained by saidplates to thereby relieve the runner of the burden of the column ofwater in the dischargek 1 e. p Ither objects and advantages will appearin the following specification, referencebe.- ing had to theaccompanying drawings, in which:

Fig. 1 is a longitudinal section of a well showing the improved pumpsuspended( therein,

Fig. 7 `is a detail perspective view of the vstationary nozzle plate,

Fig. 8vis a sectional perspective view of the runner showing it in placein the lower half of the casing, and

Fig. 9 is a development of a portion of the periphery of both the nozzleplate and the runner, illustrating the action of the nozzles. Q f

The general construction of a'rotary pump comprises a line shaft l whichis housed in a shaft casing 2 for the purpose of protecting the shaft`from the corrosive action of the water and also lpreventing theentrance of the water in the variousbearings which assist in supportingthe shaft.A

Both the line shaft and shaft casing are situated in the center of thedischarge pipe 3 which extends tothe surface where it has connectionwith acommon T 4 from which the water discharges. The stulng `box 5(Fig. 1), frame 6, driving pulley 7 and well casing 8 are all partswhich are very familiar to those acquainted with deep well um s thedischarge pipe 3 is a runner casing which is made in u per and lowersections 10 and 11 respective y. Attached at 12 to the bot- Suitablysecured at 9 to the bottom of 4 tom of the lower section 11 is an intakepipe 13 Awhich may have the customary screen tubing 14: for the purposeof keeping out the larger particles of sand. All these parts are wellknown in the art.

The invention consists of both the improvement of the runner l5 and theprovision of a peculiar nozzle plate 16 with which the runner'` isadapted to cooperate.

'It is to be observed that the nozzle plate 16 includes a llange 17which is bolted in placeat 18 between the lianges of the sections 10 and11, so that the plate 16 is rigidly held in place and' to all intentsand purposes forms a part of the runner casing. It

'is also to be observed that the nozzle plate 16 provides a cover orroof for`thelower section 11, thereby defining a chamber 19 in Which`therunner l5 rotates.

The runner 15 includes a sleeve 20 which extends into a correspondinglyshaped bore 21 in the base portion 22 of the stationary "Depending fromthe runner 15 is a tube 1.

24. This tube is long enough to extend Well into the inlet pipe 13.Arranged at the upper end of the tube is a plurality of intake orifices25 through which water discharges into the chamber 19 in the operationof the pump. It is to be observed, particularly in Figs. 4, 5 and 8,that these orifices discharge into spaces which may Well be termed watercells 26. These cells are defined by curved vanes 27 which originate atthe tube 24 and terminate in nozzles 28 at the periphery of the runner.Regarding the runner. to be turning in a clockwise direction (Fig. 5)the reader can readily see that there will be a tendency to dischargethe water in the cells 26 through the nozzles 28, and as the water isdischarged at the nozzles more is run in through the inlet 13 at thebottom.

Each nozzle opens at 29 on top of the runner 15. Only that portion ofeach nozzle adjoining the o ningl 29 is closed under neath at 30. Therest of the runner is open underneath, the bottom of the section 11,however, providing the necessaryclosure for the chamber 19. The chamber19 and water cells 26 may be regarded as one andthe same part, it/beingmerely desired to distin uish between the two in Figs. 2 and 5.

ttention is' now directed to the nozzle plate 16. The periphery of thisplate is formed into a plurality of radial blades 31 which definelpassages or nozzles 32 through which the water from the runnernozzleoutlet 29 passes into the pressure compartment or upper section10. The outer sides of the nozzles 32 are open as shown in Fig. 7 butwhen the nozzle plate 16 is inserted into the upper section 10, theseouter sides are closed, as can readily be seen in Fig. 2. The blades 31and consequentlythe nozzles 32, are disposed at an angle to the rotatingnozzles of the runner. The degree of this angle is dependyent on thedesired pressure at whichV the water is to be forced through therotating nozzles of therunner. It is sufiicient to say that the angle israther sharp, and this sharp or acute angle is adapted for an importantpurpose:`

It is a principle of hydraulics that when water is forced through apassage atv a predetermined acute angle, `none of it can slip back. Itis the adoption of 'this principle in the stationary nozzle plate 16that makes it possible to sustain 'the weight of the head of water inthe discharge pipe 3 entirely independent of the runner 15' so that thechurning, friction, additional power required,etc., attending uponpermitting the head of water to rest on the impeller, 1s entirely doneaway with.

The operation may be readily understood from the foregoing description.The plate 16 with its blades 31 and nozzles 32 (Figs. 3 and 7 )l is heldstationary by virtue of being bolted in place at 18 (Fig. 2) between thefiang'es of the upper and lower runner casing sections 10 and 11. Therunner 15, on the other hand, is freely rotatable in the chamber 19beneath the nozzle plate. It is the line shaft 1 that rotates therunner.

The reader may assume the water cells 26 (Fig. 5) to be filled withwater. Upon turning the runner in the clockwise direction indicated bythe arrow, the water will be forced towardy the narrow peripheralportion of each of the water cells and upwardly into the nozzle 28andthrough the openings 29 which appear on the top of the runner.

These openings are immediately below the the runner 15 is .forced intothepressure chamber 10 and the weight of the column of water 4issustained on top of the plate 16 and not by the runner 15, which wouldbe the case we'rek the nature of theoutlets of the runner different.,The operation of the runner causes a friction of water in the inlet orintake pipe 13, which water discharges through the orifices 25 into thechamber 19 and consequently into the water cells 26, which parts may beyregarded as the same.

While the construction and arrangement of the improved` deep well pumpas herein described and claimed, is that of a generally preferred form,obviously modifications and changes may be' made without departing fromthe spirit of the invention or the scope of the claims.

I claim 1. A pump comprising upper-and lower sections, a platestationarily secured between for and defining a chamber in the lowersecytion, nozzles formed in the cover plate, a
